If you have received Christ as your saviour, He has set you free. But every Christian has accumulated spiritual baggage that can prevent growth and fruitfulness. The good news is that you can get rid of this baggage because of your position in Christ as a Child of God.
The freedom in Christ course is one way to do this. Its open to any Christian, but its especially helpful if you feel that you are not growing as you should, or if you want to break free from destructive thought patterns or behaviours.
